| + | [https://www.uniprot.org/uniprot/RPD3_YEAST RPD3_YEAST] Catalytic component of the RPD3 histone deacetylase (HDAC) complexes RPD3C(L) and RPD3C(S) responsible for the deacetylation of lysine residues on the N-terminal part of the core histones (H2A, H2B, H3 and H4). Histone deacetylation plays an important role in transcriptional regulation, cell cycle progression, DNA damage response, osmotic stress response and developmental events. Is involved in rDNA and telomere silencing and in double strand breaks repair. Required for both full transcription repression and activation of many genes including cell type-specific genes (STE6, TY2 and HO), cell differentiation-specific genes (SPO13), genes that respond to external signals (PHO5) and TRK2. The RPD3 complexes regulate also chromosomal replication timing.<ref>PMID:10079324</ref> <ref>PMID:10359799</ref> <ref>PMID:10388812</ref> <ref>PMID:10931932</ref> <ref>PMID:11069890</ref> <ref>PMID:12089521</ref> <ref>PMID:12192044</ref> <ref>PMID:12808094</ref> <ref>PMID:14711989</ref> <ref>PMID:14737171</ref> <ref>PMID:15141165</ref> <ref>PMID:15143171</ref> <ref>PMID:15456858</ref> <ref>PMID:16286008</ref> <ref>PMID:1944291</ref> <ref>PMID:8962081</ref> <ref>PMID:8978024</ref> <ref>PMID:9512514</ref> <ref>PMID:9710596</ref> | ||

| + | The Rpd3S complex plays a pivotal role in facilitating local histone deacetylation in the transcribed regions to suppress intragenic transcription initiation. Here, we present the cryo-electron microscopy structures of the budding yeast Rpd3S complex in both its apo and three nucleosome-bound states at atomic resolutions, revealing the exquisite architecture of Rpd3S to well accommodate a mononucleosome without linker DNA. The Rpd3S core, containing a Sin3 Lobe and two NB modules, is a rigid complex and provides three positive-charged anchors (Sin3_HCR and two Rco1_NIDs) to connect nucleosomal DNA. In three nucleosome-bound states, the Rpd3S core exhibits three distinct orientations relative to the nucleosome, assisting the sector-shaped deacetylase Rpd3 to locate above the SHL5-6, SHL0-1, or SHL2-3, respectively. Our work provides a structural framework that reveals a dynamic working model for the Rpd3S complex to engage diverse deacetylation sites. | ||
